Lucky Dip really should have been included on lottery terminals from the start, because a lot of people fill in the numbers at random. The reason for its exclusion for so long was to increase the chance of a rollover (and Camelot makes a lot of money from rollovers) because Lucky Dip would use more combinations than manual selection of numbers and hence make a rollover less likely. If you wish, you can use a WWW version of Lucky Dip instead.
About 70% of lotteries around the world have a Lucky Dip facility on their terminals, though it's more commonly known as Quick Pick and was described as such in the early Camelot rule book until they decided to be "different" and change its name ! In New Zealand, 50% of players use Quick Pick, whereas in Ireland only 10% do. UK Lucky Dip sales are currently about 15% of on-line ticket sales.
